Tou-all 'whom it 'im'y coa/cem:

Be it known that I, BURTON D. KNICKER- noonnn, a citizen of the Uniteding .at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Hose ConnectionsforFaucets, of which the following is a description, accompanyingdrawings, forming a part of this specification, in which correspondingletters of' reference in the different figures indicate like parts. f

The object of my invention is tol provide a detachable connection forhe, purpose-of connecting a hose or similar uid Conduit to a faucet oruse with bath-tubs, lawn-sprinklers andthe like, which shall be soconstructed as to enable a fluid-tight joint to be made with faucetsorother iiX- tures having outletsof varying shapes and dimensions,preferably by causing the end of the faucet or other fluid eductionelement to 'connect closelyewith and embed 'itself into lavatories,

States, residreference being had to the the surface of an elasticconnecting element `around one or more openings therein, in di at ornear its center and so constructed,l

either by means of a metallic casing or otherwise, as to enable theperforation therein to communicate directl by means of a rigid case orring and provided with means for detachably locking said rigidportion tothe faucet, all of which is hereinafter more particularly described landclaimed.-

ying it applied to a faucet, Fig. 3, is a like" View of the connectionwithout the faucet,j Fig. 4, shows a plan View, and Fig. 5, 1s a ibottom view of the diaphragm.

Referring to the drawings, a represents a v funnel-like case,the body ofwhich is preferably formedfrom metal. The lower end with the hose thediaphragm being perip ierally supported 40 Water-tight joint. For thispurpose,

fer to thicken the body of the diaphragm, as'

of the case is provided with an outlet b, of smaller diameter, to whichmay be attached a. iieXible hose c. Into the upper end of the casing issecured a yielding contact `element or diaphragm d,jof soft india-rubberory other flexible elastic material having a central opening e, Figs. 2and 3, to permit the passage of iiuid directly to the hose c. The

diameter of said opening, if there be but one,

is made somewhat less than that of the smallest faucet to which plied,so that in case the faucet f is caused to project Vtherein, as maysometimes occur, the aperture Will stretch so as ,to lit tightly aroundthe outside of the faucet and form a.

I prelShown at g, so as to form an annular ridge upon its under sidearound the opening and I also prefer t0 mold radial reinforcing bossesL, Figs. 2 and 5, upon the inner face -of the diaphragm to prevent itfrom being reversed or rolled back upon itself under strong waterpressure and thereby causing a. leak when applied. to faucets smallenough to enter the opening. The diaphragm is provided With a peripheralbead i, and may be secured in place in. the casing by means of aninturned peripheral flange y', which is spun or otherwise pressedagainst a thin ring is, interposed between it and the bead. 'lhe beadbeing compressed by the metal, serves to form a. liquid-tight joint. Ascrew or rivet Z, is passed through the casing and it is likely to beap.

ring, While a pin m, is secured to said casing and ring in like mannerat a point diametripcally opposite to theu rivet l. A chain n, has oneend permanently attached to' the part Z and is adapted to be passed overthe top of the faucet .when the pin m, may be extended through one ofthe links to hold the connection rigidly in place. i

p The operation of said device is as follows: The diaphragm is firstplaced against the end of the faucet with the opening in the latteropposite to that of the aperture e. Ordinarily, the faucet opening willbe large enough to surround the aperture. Thecasing i s"then forcedupwardly until the diaphragrnv is stretched, as; shown in Fig. 2,thereby causing the end of the faucet to indent itself sutliciently intothe rubber to form a water-tight joint. While thus held, the chain 1i,is drawn over the top of the faucet and fastened in the manner describedso as to hold the diaphragm in its stretched enough-to enter the centralopening., to those \\'lio-c diameter nearly equal to that of thediaphragm.

Haring thus described my invention, l

eol

l. A coupling connection of the class described, in which are combined atunnelsliaped metallic casing having a shoulder l near its top to ,tornia peripheral supportfor a yielding diaphragm, a yielding diaphragm'provided with an upwardly extended annue said diaphragm having a centralopening, and a inetallic'ring l lar periplieifal portion,

Withinl said annular portioinvsaid diaphragm and ring. being held inplace by means o't an inwardly and downwardly turned annular flangearranged to engage the'upper edge of said metallic ring.

2. A coupling connection of the class clescribed, in which are combineda funnel` shaped metallic casinxg,r iared outwardly near its top toform. an internal shoulder, thence ext-ended upwardly, inwardly anddownwardly tofform an annular recess, a metallic ringl within and heldin place by said doWn. wardly extended poi-tion, a yielding diaphragmarranged to rest upon said shouh der with an annular portion extendedupwardly within said recess, said diaphragm having a central opening,-and means for holdingl said' diaphragm in a stretched condition againsta faucet.

il. A. couplingy connection of the class defibed, in which are combineda funne i shaped metalliccalsing flared outivardly near its top to form.an. inteinal shoulder, thence enrtenclin'gl upwardly, inwardly anddownwardly toform an annular recess, a metallic pliragni in a stretchedcondition against a;

faucet, substantially as shown and described. A

In a coupling connection ot the class described,L the combinationof. a funnel shaped casing having therein a centrally'per foratedelastic diaphragm to be pressed against the outer end of a faucetoflarger diameter than that of the perforation in said diaphragm, saidcasing being tlared eut- Wardly near its top 'to torni an iiitnrnedshoulder, thence extended upwardly, "inwardly anddownwardly to providean an nular recess for the reception of an annular flange upon saiddiaphragm, an annular-pe# ripheral flange upon said diaphragm, rigidmeans preesedagainst the inner't'ace of said flange to hold theperiphery .of said diaphragm in place against an invyard :pull and anadjustable securing chain for holding'said dia hraffin under tension aeinst the end ofA a faucet to cau-se the rim ci the latter to embeddedtherein.
